Trabeculae type of Juvenile Ossifying Fibroma of the Mandible: A Case Report

Juvenile ossifying fibroma (JOF) is a rare benign but locally invasive tumor with high recurrence potentials. It is fibro-osseous neoplasm of the jaw characterized by substitution of normal bone by fibrous tissues and newly formed calcified products such as bone, cementum or both. Juvenile ossifying fibroma is a well-demarcated lesion that differentiates it from fibrous dysplasia. This tumor may be confused with malignant condition due to rapid growth and osteolytic nature. It occurs in children and young adults. We report a 12 year old girl with a painful swelling in the right mandibular body and inferior border of the mandible referred to Mashhad Dental School in November 2013. Histological examination of incisional biopsy showed JOF. Treatment included block resection. Recurrence had not been observed in follow up from surgery up to the time of this report. JOF is a rare fibro-osseous neoplasm found in the young age group, which is considered locally more aggressive than the conventional form and spreads quickly. Therefore, it is important to diagnose the lesion early and correlate all available clinical, radiological, CT scan and histologic data for better management.
